Abstract

High pressure experiments show that addition of a reduced sulfur-rich body to Earth during its accretion would provide enough energy to power the core’s geodynamo and, by fractionating neodymium relative to samarium, would explain the observed enrichment of Earth’s mantle in neodymium-142.
